What Does the APDTY 042415 Door Lock Actuator Do?
The door lock actuator motor assembly combines the mechanical door latch with an electric motor that engages and disengages the lock mechanism. When you press the key fob, use the dashboard lock switch, or activate auto-lock while driving, the actuator motor moves internal linkages to lock or unlock the door. The latch itself secures the door to the striker on the body, holding the door closed while driving.
On 2008-2009 full-size GM trucks and SUVs, the front door assemblies integrate both functions into a single unit. When the actuator motor fails, the door may still latch mechanically but refuse to lock or unlock electrically. When the latch mechanism wears out, the door may not stay closed or may be difficult to open from inside or outside, even if the locks work.
What Are the Symptoms of a Failed Front Right Door Lock Actuator?
A failing or failed passenger-side door lock actuator typically shows one or more of these symptoms:
- Door won't lock or unlock from key fob or power lock switches, or locks and immediately unlocks
- Intermittent operation: Sometimes locks work, other times they don't
- Grinding, clicking, or buzzing noise from inside the door panel when you try to lock or unlock
- Door won't open from inside handle, outside handle, or both
- Door won't stay closed or pops open while driving
- Check Engine or security system warning lights if the body control module detects a latch fault
If only the front right door exhibits these symptoms while other doors work normally, the actuator assembly on that door is the likely culprit. The integrated design means you replace the entire latch and actuator as one unit rather than servicing individual components.

How Do You Replace a Front Right Door Lock Actuator?
Replacing the front right door lock actuator requires removal of the interior door panel and disconnection of door linkages. This is an intermediate-level repair suited for DIYers with basic hand tools and patience. Always consult a factory service manual for your specific vehicle year and model.
General installation steps:
- Disconnect the battery to prevent accidental window or lock activation and potential shorts.
- Remove the door panel: Take out screws, release plastic clips, disconnect window and lock switch connectors, and lift the panel off.
- Peel back the moisture barrier (plastic sheet) to access the latch assembly inside the door.
- Disconnect the electrical connector from the actuator and unclip any door lock rods or cables attached to the latch.
- Remove mounting bolts securing the latch assembly to the door edge (typically three Torx or hex bolts).
- Maneuver the old latch out through the access hole in the door frame.
- Install the new APDTY 042415 assembly in reverse order: position the latch, secure bolts, reconnect rods and cables, plug in the electrical connector.
- Test operation before reinstalling the door panel: reconnect the battery, check lock/unlock from fob and switches, verify door opens and closes smoothly.
- Reinstall the moisture barrier and door panel, ensuring all clips and screws are secure.
Work carefully when handling interior door rods and cables—plastic clips can break if forced. If you're uncomfortable with interior door panel removal or linkage work, a professional technician can complete the replacement in about one hour.
Frequently asked questions
Will APDTY 042415 fit my 2008 Tahoe built in Mexico?
No. APDTY 042415 fits only USA or Canada-built vehicles. Check your door jamb sticker for country of manufacture. If your vehicle was built in Mexico, order APDTY-120321 instead.
Can I use this actuator on the driver side or rear doors?
No. APDTY 042415 is designed specifically for the front right passenger-side door. Driver-side and rear door actuators have different mounting points, connectors, and internal linkages.
Do I need to program or calibrate the new actuator?
Typically no. The actuator is a plug-and-play replacement. However, some vehicles may require a door lock relearn procedure using a scan tool if the body control module stores a fault code. Test operation first; if locks don't respond, clear codes with a scanner.
What OE part numbers does APDTY 042415 replace?
APDTY 042415 replaces GM OE part numbers 20783852, 25873485, 25876388, and 25945754. Verify your original part number or VIN compatibility before ordering if you are unsure of your vehicle's build location.
